Abstract
An R.F. balanced mixer comprises on an insulating
substrate (3) with opposed major surfaces a balanced first
transmission line having a pair of conductors (18, 19) on a
first major surface and an unbalanced second transmission
line having a strip conductor (15) on one major surface and a
ground conductor (13) on the side of the substrate (3) remote
from the strip conductor (15). Two diodes (24, 25) are
conductively connected between the pair of conductors (18,
19) of the first line and the strip conductor (15) of the second
line to form an arrangement operable as a 180° hybrid
junction, the first line coupling an R.F. signal to the diodes
(24, 25) and the second line coupling an L.O. signal to and an
I.F. signal from the diodes (24, 25). To reduce the impedance
of the I.F. signal ground return path and inhibit resonant
effects, the pair of conductors (18, 19) of the first line to
which the diodes (24, 25) are respectively connected are on
the same major surface as the strip conductor (15) of the
second line and are coupled to the ground conductor (13) of
the second line by means which include conductive connec
tions (e.g. 33, 34) through the substrate (3) and which present
a low impedance to the L.O. and I.F. signals.
